The AirTAC GR20006JNTK AirTAC Air Pressure Regulator, NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT1/8" ports, ordered without a gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR20006JNTK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it contains no filter, no bowl and no lubricator. This GR200 unit is set up with a 1/8 in NPT port, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). A reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. No pressure gauge is fitted with this code, and no mounting bracket is included; the GR body is also panel-mountable. Its operating temperature window of -20 to 70 C is wider than the rest of the G-series family.
This is a genuine AirTAC part. The GR200 is the smallest size in the GR range, which steps up through 300, 400 and 600 sizes with larger ports for higher flow demand. Across the series you can order G (BSPP) or NPT threads in place of the PT standard, add a gauge, omit the reverse valve, or include a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Set a stable, reduced pressure feeding a small bench-mounted pneumatic press or clamping fixture, with the fitted check valve holding the set pressure if the shop-air supply drops.
Regulate the supply branch feeding sealing jaws or small actuator cylinders on a packaging line, keeping the working pressure consistent as other machines on the same header draw air.
Feed a compact gripper or suction circuit on a pick-and-place station, where the 1/8 in port suits tight panel space and the check valve prevents gripper pressure decaying on a supply interruption.
Start with the port step: GR200 carries the 1/8 in port, and the GR300/400/600 sizes step up to larger ports for larger air demand - match the size to the flow your circuit needs, not just the pipe thread. Next, decide the options this code carries: the J in GR20006JNTK means no mounting bracket (order a bracketed variant if you want panel or surface fixing), N means no gauge is fitted (a gauge variant can be ordered with MPa, psi or bar scale), and K means the reverse/check valve is included. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated figure, so send us your application details and we will confirm the right size against the datasheet before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as characteristic curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The N in GR20006JNTK means no pressure gauge is supplied, which is a valid catalogue configuration if you already read the set pressure elsewhere or set it with an external gauge. If you want local indication, order a GR200 variant with a gauge: an embedded square gauge is available, with MPa, psi or bar scale, and an external round gauge is also a catalogue option.
